Got a link from a fellow jet flier a few weeks ago for a replacement battery for the Vector Airpro (model#VEC256) 260PSI 12V cordless air compressor. I'm sure a lot of you out there may have this same air compressor and need a new battery by now, so here's the link. Buy two and shipping is free. The battery is a drop in fit.

Tandy DMU123 Battery (12V 2.8Ah)
Item# I-SLA1039-compatible-AB48098
